This bug is forwarded from ubuntu bug tracking system:
https://launchpad.net/distros/ubuntu/+source/gnumeric/+bug/72966

Original description:
"I launched Gnumeric accidentally by double clicking on a file called "industries.csv" which is 1 byte long (a newline character, 0x0a).

For what it's worth, Gnumeric also crashes when opening (double click in nautilus, use gnome-open, or launch Gnumeric first and choose file->open from the menu) an empty file called "empty.csv" but succeeds on similarly named 1 byte files containing a comma (0x2c) or tab character (0x09).

Bug Buddy reports the following error, so I'll just paste the traceback details below..."


I fount that giving null to strchr function caused these problems and here's
a little one-liner for fixing this.
